- Description
-
Snakebark maple is an understory small tree or large shrub in the maple family (Sapindaceae) with a rounded habit. This tree's name is in reference to the state of Pennsylvania where it is native. It is also native to NC mountain areas where it can be found in dry to mesic forests.
It prefers partial shade and well-drained moist soils. It tolerates heavy shade very well and performs best in cooler summers so it struggles in the south.
The interesting bark on stems and young trunks have white striped markings giving it the common name of snakebark. The shape of the leaves are supposedly the shape of a goosefoot giving it the common name of goosefoot maple. The bright yellow leaves provide fall interest and the unusual bark provides winter interest.
This tree will do well as an understory tree or shrub in woodland areas. Protect it from full sun as leaves may scorch.
Insects, Diseases, and Other Plant Problems: Potential disease problems include verticillium wilt, leaf spots, tar spot, canker and root rots. Potential insect problems include aphids, scale, borers and caterpillars. Mites may appear. See potential insect and disease problem fact sheets to the left.
The Clemson Cooperative Extension Home and Garden Information Center has a factsheet on common maple diseases and insect pests.

- Uses (Ethnobotany):
- The Striped Maple has limited uses. Its porous and fine-grained wood has occasionally been used by cabinet makers for inlay material. Whistles can be carved easily from branch sections. Native Americans reportedly used the wood to make arrows and the bark to make a beverage. Farmers in the American colonies and Canada reportedly fed their cattle both dried and green leaves in the winter; in the spring, when the buds had begun to swell, they turned their horses and cows into the woods to browse on the young shoots. Native Americans used the Striped Maple to treat a variety of ailments including bronchial and kidney troubles, colds, and coughs.
